Benefits of technology

[0021]Furthermore, the described features, advantages, and characteristics of the invention may be combined in any suitable manner in one or more embodiments. One skilled in the relevant art will recognize that the invention may be practiced without one or more of the specific features or advantages of a particular embodiment. In other instances, addi

Problems solved by technology

Existing circuitry to shift the phase of a radio frequency (“RF”) signal by a variable amount is expensive, bulky, and not well-suited to integration on a chip.
Because the circuitry must be replicated for each antenna in the phased array, the overall system cost becomes prohibitive for many applications.

Embodiment Construction

[0031]As will be appreciated by one skilled in the art, aspects of the present invention may be embodied as a system, method or computer program product. Accordingly, aspects of the present invention may take the form of an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, micro-code, etc.) or an embodiment combining software and hardware aspects that may all generally be referred to herein as a “circuit,”“module” or “system.” Furthermore, aspects of the present invention may take the form of a computer program product embodied in one or more computer readable medium(s) having computer readable program code embodied thereon.

[0032]Many of the functional units described in this specification have been labeled as modules, in order to more particularly emphasize their implementation independence. For example, a module may be implemented as a hardware circuit comprising custom VLSI circuits or gate arrays, off-the-shelf semiconductors s...

Abstract

An apparatus, system, and method are disclosed for phased array antenna communications. A phased array antenna tile includes a plurality of antenna elements. A beamformer module is integrated into the phased array antenna tile. The beamformer module is electrically coupled to each antenna element to process directional signals for the plurality of antenna elements. A plurality of cascadable connection points are disposed along a perimeter of the phased array antenna tile for connecting the phased array antenna tile to one or more additional phased array antenna tiles.

Description

CROSS-REFERENCES TO RELATED APPLICATIONS[0001]This application claims priority to U.S. Provisional Patent Application No. 61 / 259,608 entitled “APPARATUS, SYSTEM, AND METHOD FOR INTEGRATED MODULAR PHASED ARRAY TILE CONFIGURATION” and filed on Nov. 9, 2009 for Karl F. Warnick, which is incorporated herein by reference.FIELD OF THE INVENTION[0002]This invention relates to phased arrays and more particularly relates to integrated modular phased arrays.BACKGROUNDDescription of the Related Art[0003]Phased array systems employ an array of antennas to permit directional signal reception and / or transmission. The array may be one-, two-, or three-dimensional. Arrays operate on a principle similar to that of a diffraction grating, in which the constructive and destructive interference of evenly spaced waveforms cause a signal of interest arriving from one angular direction to be strengthened, while signals from other angular directions are attenuated. By separately controlling the phase and th...
